Section 2 Installation
DAX-1/DAX-3
NOTE:
The Remote Commands are referenced to the customer ground, which is allowed
to float 30V above or below the system ground. It is recommended to connect all
Command signal returns to a GNDC connection. All remote commands are opti-
cally isolated and have a 10mA nominal sink current. The maximum allowed
voltage is 30V; the minimum is -2V. With the exception of RMT OFF and RMT
RF MUTE, all remote commands are disabled when operating in Remote Dis-
able. The majority of commands are momentary and must be pulled to their
active level for a minimum of 200 mS to be registered. However, RMT RF Mute
and RMT Power Limit SEL are steady-state active low signals, while RMT Digital Pres-
ent is a steady-state active high signal.
NOTE:
Digital Present Return must be connected to a DEXSTAR/ePAL ground. If RMT
Digital Present is not being used, this return line must be connected to GNDC.
J5-1 GNDC - Command return
